- Flash-Lights, of which the following is a' llE lUU hi a rrasn-nrnr."

New York, in t'he" county of New York and State of New York, have invented certain new and useful llmprovementsin Pocket specification.

This invention relates to pocket lights and more particularly to electric pocket flash lights having the electric light, battery and controlling means'simply and compactly arranged within a suitable casing.

One of the objects of the present invention is to provide a simple and practical electric pocket flash light of the above gen eral character having few parts whereby the same may be easily and quickly assembled and manufactured at a minimum expense.

A further object is to provide "a device of the first above-mentioned character in which 1 the parts are so positioned and arranged as to pent movement and rattling thereof when the same is handled and consequent wear of e parts.

Other obects will be in part obvious from the annexe drawings and in part indicated analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts, in the unique relations of the members, and in the relative proportion-in disposition thereof, all as more comp etely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated. by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure, and in such drawings, like characters of reference denote corresponding parts throughout all the views, in which- Figure 1 isa longitudinal sectional view of the completedevice in normal position;

Fig. 2 is a similar view of a portion of the device showing a modification;

Fig. 3 is a similar view showing a modisurfaces of the end of the battery and to be of the battery cell of a modifiedconstruction.

In this view, the usual ineulat 1n connection therewith by the following and hpecticattonof ll'iettem fatent. f. Patented iwwe 4t, 1911])? Application area ae a m'aa an; Serial No. maria.

jwrapping or sheath of the shellvis shown in section in the interest of clearness.

Referring now to the drawings in detail and more particularly to Fig. 1, 5 designates an outer cylindrical shell made of a single piece of tubing having stamped out threads at 6 at one end into which a lamp socket 7 is adapted to be screwed. A small electric bulb 8 provided with a base 9 is adapted to be screwed into the socket plug and is provided at its rear end with a contact 10 adapted to be engaged by one of the terminals 11 of a cylindrical battery cell 12 contalned 1n the body 5. The opposite end of this battery is provided with a contact plate 13 adapted to be engaged by a push button 14 mounted in a threaded plug 15 screwed into the threaded end 17 of the easing 5. The contact end 16' of the push button 14 has riveted thereto a washer 20 to prevent removal thereof by the reaction of a coil spring 18 normally holding the push button in the position shown in Flg. 1.

This washer'20 surrounds the pin near its contact end and lies adjacent the plug 15. An insulating washer 21 is carried by plug 15 and is adapted to hold the battery firmly in place and prevent movement or rattling thereof. It will be noticed in the form shown in Fig. 1 that this washer is die stamped out-of suitable insulating material to closely fit an annular groove formed by two shoulders 22 and 23 in plug 15 and is held positively thereby as said plug is screwed into or out of the casing. The washler may be of elastic or non-elastic materia In Fig. 2, substantially the same arrange ment of parts is to be found except that an insulating and non-rattling washer 24 is made slightlylarger andplug 15 is provided with only one shoulder 25 upon which the washer is forced and is held in place by its frictional contact. 7

In Fig. 3, a still further modification of the washer is shown. In this modification the washer 26 is provided with a recess formed by an enlarged shoulder 27 into which the end of the battery 12 fits snugly. lhis washer is so shaped as to' grip the outer the battery with respect to the casing 5. In

the inside of the metal this manner wear 0 tube or other construction material is eliminated, and the insulating or non-conductive material, preferably fiber, of the washer 26 will permlt the operation of the push button or plunger 14 therethrough. The manner in which the parts are constructed and fitted one within the other ermits the plug casing and battery to be talEen apart without danger of loss of the washer, as would occur if the washer were loosely mounted instead of closely fitting one of the parts with which it is associated.

Fig. 4 shows an insulating washer 27 of the same outside size and diameter as the outside casings of the battery cell 12 and forms one of the parts of the battery construction. It isinclosed and held permanently in place by the common insulating inatenal used to cover and finish the battery casings.

It is believed that the method of use and operation of a device of this character is clear and will be understood by those familiar with the subject. The device may be said to comprise but three parts, that is, the casing with its lamp, the battery and the push button.

This method of construction and use of the parts as shown does away with any air opening or aperture through the shell case,

thus protecting the batteryfrom any atmospheric action, affordin clearly a damp and moisture proof outsi e case and provides a confined air envelop around battery and interior, when allparts are screwed together.

This invention is simple and practical in construction, inexpensive to manufacture, and accom lishes, amon others, all of the objects and advantages a ove set forth. v

I realize that conslderable variation is possible in the details of construction and arrangement of parts without departing from the spirit of my invention, an do not intend to limit myself to the specific form shown and described. 1
